Abstract

The utility model discloses an outer cover with folding doors used on a numerically-controlled machine tool. The face of the outer cover adopts the folding doors that have transparent windows in the frame, which have a wide view and a wide opening range and are convenient to operate. The fixed side of the folding door is connected with a cover body by means of upper and lower shafts and can rotate. The lower end of the switching side of the folding door adopts a guiding sleeve that can rotate and is matching fixed on a cell guide of the cover body used for the sliding and bearing functions. The upper end of the switching side of the folding door adopts a ball bearing and is supported on a guiding rail slot of the cover body to move. The two doors are hinged and folded by means of the upper and lower shafts. The whole folding doors adopt a back slant design, take advantage of the moment formed by the deadweight force to close the doors tightly; the folded and hinged positions are embedded with a tensional spring; and the folding door can be opened with legerity by means of the elasticity. Therefore, the utility model is suitable for all the numerically-controlled machine tools, such as the vehicle, the mill, the machining centre and the composition of the vehicle and the mill, etc, especially applicable for the numerically-controlled machine tool for the mini-type teaching that requires a compact appearance and a wide view.

Description

A kind of folding gate-type Digit Control Machine Tool outer cover

Technical field

The utility model relates to a kind of Digit Control Machine Tool outer cover, and particularly a kind of folding gate-type Digit Control Machine Tool outer cover is the innovation to the traditional machine tool outer cover.

Background technology

Machine tool outer casing is an indispensable part of lathe, complete machine tool outer casing, can prevent iron filings, cooling fluid ejecta pollution environment effectively on the one hand, preventing that the workpiece, the tool holder that get loose from coming off causes personnel's injury accident, clean safe operating environment is provided, satisfies relevant safety standard; On the other hand, moulded attractive in appearance, can be lathe and bring perfect outward appearance sensation.Digit Control Machine Tool is the machine-tool that has characteristics such as high accuracy, high efficiency, high automation and high flexibilityization in the mechanical production devices, the more totally enclosed type outer cover that is designed to, and positive single fan or the biparting horizontal sliding door of adopting usually, door is installed on the outer cover guide rail.The door of this type structure is opened wide the restriction that scope is subjected to machine tool outer casing front lateral dimension, and the former is often less than half of the latter, and door body structure require abundant firmly, limiting the size of penetrating observation window area on it.This junior machine to the shape requirement compactness, the visual field require broad teaching extremely unfavorable with lathe.

The utility model content

The purpose of this utility model is to provide a kind of folding gate-type Digit Control Machine Tool outer cover, its open wide scope wealthy, have a wide sphere of vision, folding is lightly reliable, easy to operate, safety.

For achieving the above object, the utility model is realized by following technical measures:

Outer cover cover body of the present utility model front is provided with framework transparency window formula folding door.The folding door fixed edge is connected with cover body and can rotates by last lower rotary shaft; Rotatable guide pin bushing is adopted in lower end, folding door folding limit, cooperates the guide pillar that is fixed on the cover body to slide double load-bearing, and ball bearing is adopted in the upper end, is bearing on the cover body guide-track groove and moves; Hinged folding between the two fan doors by last lower rotary shaft.The design of the whole employing of folding door rear-inclined utilizes the door body to make a firm closure from the moment that gravity forms, and folds the nested torsion spring in hinged place, lightly opens wide by elastic force.

This folding door is divided into two fan doors, and is hinged folding by upper and lower rotating shaft between the two fan doors.Described folding door also can be more than two fans, and connection therebetween is hinged by rotating shaft.

The utility model has the following advantages compared with the prior art:

1, the positive framework transparency window formula folding door that adopts of outer cover is had a wide sphere of vision, and it is wealthy to open wide scope, handled easily.All Digit Control Machine Tools such as being applicable to car, milling, machining center, turnning and milling are compound, be specially adapted to the shape requirement compactness, the visual field requires broad small-sized teaching Digit Control Machine Tool.

2, the folding door fixed edge is connected with cover body and can rotates by last lower rotary shaft; Rotatable guide pin bushing is adopted in lower end, folding door folding limit, cooperates the guide pillar that is fixed on the cover body to slide double load-bearing, and ball bearing is adopted in the upper end, is bearing on the cover body guide-track groove and moves; Hinged folding between the two fan doors by last lower rotary shaft.

3, the whole employing of folding door rear-inclined design utilizes the door body to make a firm closure from the moment that gravity forms, and folds the nested torsion spring in hinged place, lightly opens wide by elastic force.

Description of drawings

Fig. 1 is overall structure figure of the present utility model;

Fig. 2 is the folding door vertical view;

Fig. 3 is that folding door folding side door body is connected side view with cover.

The specific embodiment

Shown in Fig. 1～3, in Fig. 1, the utility model is made up of cover body 1 and folding door 2, and folding door 2 adopts the frame-type of transparency window 3, has a wide sphere of vision, and it is wealthy to open wide scope, handled easily.

In Fig. 2, folding door 2 fixed edges are connected and can rotate with cover body 1 by last lower rotary shaft 4,5; Rotating shaft 6 on passing through in the folding hinged places of two fan doors, lower rotary shaft 8 be nested torsion spring 7,9 respectively, by elastic force F _BulletLightly open wide.

In Fig. 3, rotatable guide pin bushing 10 is adopted in lower end, folding door 2 folding limit, cooperates the guide pillar 11 that is fixed on the cover body 1 to slide double load-bearing, and ball bearing 12 is adopted in the upper end, is bearing in motion on the cover body guide-track groove 13.Make folding steadily, reliably.

As Fig. 2, shown in Figure 3, folding door 2 and the cover body 1 positive consistent rear-inclined design of adopting utilize the door body from gravity F _HeavyThe moment that forms makes a closure.
